A population of 40 rats living near a restaurant dumpster is growing at a monthly rate of 50%
goldenfox [79]

[(40 ÷ .5) Y] + 40

Parentheses are rat growth

Brackets are rat growth by how many years or just exclude that and the brackets if you don't need to know how many years are there are

The 40 is the amount of rats already there

Growth of rats plus the amount already there.

I'm probably wrong lol
